Some camo cloth stapled to some 1x2's that you could pound into the ground and lay brush over could conceal you from the front. As long as you have some natural overhead cover, or just keep your head really low, it could work pretty well.

I just built two field blinds recently. Took 5 " metal stakes that you might find at Lowe's for a light duty fence and attached a green plastic fencing to it with zip ties. Attached the burlap camp cloth to that.

Then I added pine and cedar brush, which I ziptied along the the blind. It came out really well and took about 45 minutes to build.
